A variety of 4-methoxysalicylates and related polyketide-type phenols are regioselectively prepared by formal [3+3] cyclocondensations of 1,3-bis(trimethylsilyloxy)-1,3-butadienes with 3-oxo-orthoesters. Cycloalkyl-substituted salicylates were prepared for the first time.

A variety of 3-chlorosalicylates were prepared by one-pot cyclizations of the first reported 4-chloro-1,3-bis(trimethylsilyloxy)buta-1,3-dienes with various 1,3-dielectrophiles, These include cyclizations with 3-silyloxy-2-en-1-ones, 3-aryl-3-silyloxy-2-en-1-ones, 1-methoxy-1-en-3-ones, 1,1-bis-(methylthio)-1-en-3-ones, 3-oxo orthoesters, 1,1,3,3- tetraethoxypropanes, 1,1-diacetylcyclopropane, and 3-formylchromones.
